Dutch news agency ANP published a report on the Volkskrant-article; it appeared in most Dutch media. As ANP is associated with the international news agency AFP, very soon translations in Chinese, Czech, English, French, German, Hungarian, Japanese, Portuguese, Rumenian, Slovenian and Spanish followed.

Unfortunately the translators who worked on the French, German and Spanish versions introduced fantasy in their articles, claiming that we -Van den Born and Droog - had studied the pencil strokes on the NIOD watercolor, and concluded that it was almost certainly not painted by Hitler but possibly by Reinhold Hanisch, the first known 'Hitler' forger.

Well: we did not study the pencil strokes, and even if we had, we could not have concluded anything based on it, by lack of reliable comparison material.

We don't know who painted the NIOD watercolor. There's no direct evidence linking this work to a particular painter.

We also did not comment on the quality of the NIOD-watercolor attributed to Hitler.
